Extending the Standard Model with the Peccei-Quinn symmetry and/or supersymmetry, compelling dark matter candidates appear. For the axion, the neutralino, the gravitino, and the axino, I review primordial production mechanisms, cosmological and astrophysical constraints, experimental searches, and prospects for experimental identification.31 pages, 14 figuresHigh Energy Physics - PhenomenologyAstrophysicsHigh Energy Physics - Experimenttext
